Abstract
Description
[Technical Field]
[0001] This invention relates to a device that can be attached to the inner wall of a conventional roll paper holder to enable the roll paper to be used hygienically. [Background technology]
[0002] Conventional roll paper cutters have a cutting blade on the front edge of the top cover, and after cutting the required length of paper, when you try to grab the end of the roll again and pull it out, this end sticks to the outside of the roll, making it difficult to use and extremely unsanitary. It is also particularly difficult for people with visual impairments to pull it out using only their sense of touch. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent Publication No. 2021-007558 Summary of the Invention [Problem to be solved by the invention]
[0004] In typical conventional roll paper holders (hereinafter referred to as paper holders), the end of the paper is pulled out to the required length, then pressed down with the top cover of the roll (hereinafter referred to as the top cover) and pulled upwards to be cut. However, when trying to pull out the end of the paper again, this end becomes stuck to the outside of the roll, so when pulling it out again, it is necessary to scratch it from below with your fingernail or push the bottom of the roll paper against the wall with the palm of your hand to let the end hang down and then pick it up, which is not only difficult to use but also very unsanitary.
[0005] Also, it is difficult for people, especially those who are visually impaired, to easily and cleanly remove the paper end. The purpose of this invention is to solve the above-mentioned drawbacks and to provide an attachment-type roll paper cutting aid that can be easily attached to most commercially available ready-made paper holders by simplifying its structure and can be offered at low cost. [Means for solving the problem]
[0006] To achieve the above objectives, the attachment-type roll paper cutting aid of this invention has support sections with holes drilled into both the left and right sides of a roughly U-shaped base plate, and one side of a round rod bent into a roughly U-shape is inserted into both support sections and pivoted so that it can swing freely. The bar on the opposite side of this round rod (hereinafter referred to as the bar) is configured to be placed in contact with and parallel to the axial direction at any position on the top surface of the roll paper. Furthermore, the problem is solved by providing a structure in which a fixing device is provided on this base plate so that the base plate can be fixed at any position on the inner wall side of the paper holder.
[0007] The attachment-type roll paper cutting aid configured as described above (Fig. 3) is attached to the inner wall side of the existing paper holder body using double-sided tape, screws, or both. Here is the procedure for replacing the roll paper. When using, lift the bar attached to the shaft along with the top cover, set a new roll paper in the paper holder, and lower the bar. Then, pull the outer edge of the set roll paper forward so that it passes over the top of the bar (Figure 1). Next, lower the top cover, pull out the amount of paper you need, press down on the top cover, pull up the paper and cut it. The next time you use it, the end of the paper will be hidden by the top cover and will not be able to be picked up with your fingers, but it will be resting on the top surface of the bar a few centimeters inside the top cover. After lifting the top cover, you can pick up the paper by sliding your fingers from both ends or one side of the bar inward, or by simply picking up the floating part (Figure 3). In addition, the appropriate weight of the bar generates appropriate friction at the contact point between the bar and the rolled paper when the paper is pulled out, preventing excessive rotation of the rolled paper. Furthermore, because the paper is soft and the bar is hard, the end of the paper can be easily identified and pulled out using only the feel of your fingers, without having to look at the end of the paper. [Effects of the Invention]
[0008] In the past, after cutting the paper with the top cover, when you opened the top cover again to pull out the end of the paper, you had to operate it in an unsanitary manner, such as by directly touching the rolled part of the roll paper, making it difficult to use.However, with this device, the bar separates the rolled part from the end of the paper to be pulled out, so you can slide your fingers over the top of the bar to pick it up and pull it out without directly touching the roll paper itself, making it more hygienic to use.
[0009] Also, even if you pull the end of the paper too hard, it no longer rotates too much and the paper no longer comes out too much.
[0010] Even if you are blind, you can now use it just by feeling it with your fingertips.
[0011] In addition, the attachment-type roll paper cutting aid of this invention can be easily attached to most types of existing products by using double-sided tape, screws, or both to the inner wall surface of the main body of an existing roll paper holder.
[0012] Furthermore, due to its simple structure, it can be manufactured inexpensively, and can be changed into a hygienic roll paper cutter that is durable, easy to use, and durable. [Brief explanation of the drawings]
[0013] [Figure 1] This is a perspective view of the device attached to an existing paper holder, with a new roll of paper installed and the top cover open. [Figure 2] FIG. 2 is a front view of FIG. [Figure 3] The cross-sectional view of FIG. 2 taken along the line AA is shown, along with a reference state of use of the present invention. [Figure 4] 4A to 4C are cross-sectional views showing the changes in the movements of the various parts when the device is in use. DETAILED DESCRIPTION OF THE INVENTION
[0014] Supports are formed on both sides of the base plate, and one side of a roughly U-shaped round bar is axially attached to the support. The bar swings in response to changes in the amount of paper wound on the roll, and is always positioned parallel to the axial direction of the top surface of the roll. A fixture is then provided so that the base plate can be attached to the paper holder. [Example]
[0015] An embodiment will now be described with reference to the accompanying drawings. (Figure 1) A metal base plate 1 was bent into a U-shape to form support portions 1a on both sides. Holes were then drilled to support one side 2a of a round rod across the support portions 1a on both sides. One side 2a of a metal round bar bent into an approximately U-shape is inserted and attached to the shaft, and the bar 2b on the opposite side of the round bar swings to accommodate the increase or decrease in the amount of roll paper, so that it can always be placed in parallel contact with any position on the top surface of the roll paper 7 (Figure 4).
[0016] The material, shape, dimensions, etc. of each component are shown. The base plate 1, which is bent into an approximately U-shape and formed as a single unit, is a stainless steel plate with a thickness of 1.0 mm, and both sides are bent at approximately right angles to form a support portion 1a, in which a hole (hole diameter 4.2 mm) is drilled to support one side 2a of a round bar.
[0017] Similarly, the metal round bar 2 bent into a roughly U-shape is made of stainless steel (COLD material) and has a diameter of 4.0 mm. The length of one side 2a of the round bar on the side where the shaft is attached is 120 mm, and the length of the bar 2b on the opposite side on the side where the roll is placed is approximately 120 mm, a few millimeters longer than the axial width of the roll paper (usually 105 to 115 mm). With these dimensions, the inside dimensions of the left and right side walls of most pre-made paper holders are 125 mm, so even if bar 2b swings up and down, it will not interfere with these side walls (Figure 2). In addition, the length (center line) of the part 2c connecting the side 2a of the round bar and the bar 2b is approximately 60 mm, which can be used with most existing paper holders as long as it is within a tolerance of plus or minus 3 mm (Figure 1). Furthermore, if the weight of the stainless steel (COLD material) bar 2b resting on the top surface of the roll paper is set to approximately 14.5 grams, it is possible to generate a moderate amount of friction that is easy to handle when pulling out the paper end 7a.
[0018] The sharp corners of both the base plate and the round bar are made safe by replacing them with corners or rounded shapes. Furthermore, in order to allow the base plate 1 to be fixed at any position on the wall-side inner surface 4a of the paper holder 7, double-sided tape is provided on the base plate 1 as a fixing device 5, and screw holes (hole diameter 4.0) are provided so that the base plate 1 can be firmly fixed as needed.
[0019] The operating procedure is explained below. See Figures 1 and 3. First, the replacement procedure: Open the top cover 4b and bar 2b and install the new roll of paper 7. Then, lower the bar 2b and pull the paper end 7a outward from the top of the bar 2b. Then, lower the top cover 4b to hold it down while pulling up the paper end 7a and cutting it. When using it next time, open the top cover 4b, feel for the paper end 7a resting on the bar 2b with your fingers, grab it, pull out the required length forward, lower the top cover and cut it in the same way. It also offers the convenience of being able to cut the paper in the normal way without using this auxiliary tool, i.e., even if the paper end is below the bar. [Explanation of symbols]
